C Program to Calculate Simple Interest based on given values.

#include<stdio.h>

int main()

{

 float p, r, n, si;

 

 printf("Enter your principle amount:");

 scanf("%f",&p);

 

 printf("Enter your rate of interest:");

 scanf("%f",&r);

 

 printf("Enter number of years:");

 scanf("%f",&n);

 

 si = (p*r*n)/100;

 

 printf("Simple Interest is %.2f", si);

 return 0;

}

Output of program

Enter your principle amount:1000

Enter your rate of interest:12

Enter number of years:2

Simple Interest is 240.00
